PDL 600 Series switches use grid plates that allow up to 6 mechanisms to be installed on each plate and are complete with a high quality plastic cover plate which conceals all fixings. The mechanisms are front mounted for safety, they cannot be pushed backwards into the wall box accidentally.
All 600 series mechanisms fit these grids. Up to 6 switch mechanisms are easily fitted to a grid but there can be space or loading issues on a grid when fitting combinations of mechanisms - for instance dimmer mechanisms need to be downrated when fitting more than one to a plate and telephone mechanisms may not always be able to be mounted adjacent to each other. If in doubt, please ask for assistance. PDL 600 Series Brochure.pdf
